Chick-fil-A has welcomed back their seasonal Peppermint Chip Milkshake, and to celebrate, they’re giving the treats away.

Through Dec. 13 — while supplies last — Chick-fil-A welcomes people 13 and older to The Whoopsery, a kitchen where every mistake is turned into something wonderful. When you make a “failed” recipe on the site, it turns into freebies for you and someone else.

Pick two ingredients and a blender speed, and although your creation is sure to fail, the baker inevitably likes what you created — and offers to send you the recipe for your new Chick-fil-A secret menu item, plus two free Peppermint Chip Milkshakes (one for you and one for a friend).

The only downside? You have to wait for the recipe and coupon to arrive in the physical mail. There’s no telling how long it’ll take to arrive.

The Whoopsery is part of Stories of Evergreen Hills, Chick-fil-A’s annual animated holiday stories.
